IP masquerading is a process where one computer acts as an IP gateway for a network. All computers on the network send their IP packets through the gateway, which replaces the source IP address with its own address and then forwards it to the internet. Perhaps the source IP port number is also replaced with … The SNAT target requires you to give it an IP address to apply to all the outgoing packets. The MASQUERADE target lets you give it an interface, and whatever address is on that interface is the address that is applied to all the outgoing packets.

IPMASQ works perfectly with LAN technologies like Token Ring, Ethernet, FDDI, and dial-up connections. SNAT works with static IP addresses. MASQUERADE has extra overhead and is slower than SNAT because each time the MASQUERADE target gets hit by a packet, it has to check for the IP address to use. IMPORTANT: It is still possible to use MASQUERADE target with static IP. Be aware that it will add extra overhead (to compute). Port Address Translation(aka PAT, Masquerading, Dynamic NAT), this is where any number of IP's are traslated to at least 1 ip.
